Most Common Causes of Diarrhea

You're out on a date with someone you really like and all of a sudden you feel that recognizable aching in your stomach. Diarrhea always occurs at the most inconvenient time. Everyone knows what diarrhea is, but few know the exact causes of this aggravating condition.

Infections

Foods

Medications

• Many prescription drugs can cause diarrhea, including antibiotics, cancer-related drugs, blood pressure medication and anti-inflammatory drugs.

Digestive Disorders

Warning

• Contact your doctor or seek emergency care if you are suffering from diarrhea and also have blood in the stool, intense abdominal pain or dehydration.
